Work Experience
Front-end Architect
2022 - 2023
Hospitality Digital GmbH - Main Hospitality Digital GmbH
- Created a set of React component libraries and architected their structure and principles. The visual design was tailored for B2B systems, and the usage of the component library unified the development and design effort between six DISH products.
- Reused components throughout the products, while the component library team added functionality and solved problems instead of solving them in every product separately, saving a significant amount of developers' work.
- Created a unified design that helped the end users feel like they were using products created by the same brand and signified brand awareness.

Experience
INVL Pension Fund Self-service Portal
https://savitarna.invl.comA pension fund self-service portal where users onboard, sign the agreements for their pension, track the fund performance and fill out know-your-customer (KYC) forms. Portal serves 250,000+ users.
I upgraded the self-service application from legacy technologies to TypeScript and React-based single-page-app with a . NET-based back end. I also used the Strangler pattern for a smooth transition of API and led the redesign of the UX to suit the users' needs better.

INVL Authentication and Identity Server
https://savitarna.invl.comA pension fund self-service portal where users onboard, sign the agreements for their pension, track the fund performance and fill out know-your-customer (KYC) forms. Portal serves 250,000+ users.
I architected a complex identity and authentication server used as a source of truth for all means of authentication for the organization.
The identity part centralized organization's users' identities under a single system and enabled all microservices to integrate it easily. The authentication server included various mechanisms for external and internal users to sign in. These include traditional username and password flow, two different qualified digital signature services, Azure AD single sign-on (SSO), and several legacy authentication mechanisms.
The authentication server's API was OAuth 2.0 compliant and used specification extensions such as RFC 8628 Device Authorization Grant and RFC 6749 Authorization Code Grant.
